FT_GAMEJAM(1) 42 Student-Run Events Manual FT_GAMEJAM(1)


ft_gamejam -- create the best games possible in a short amount of time


Standard industry events library (libevent, -levent)


#include "libft.h"


ft_gamejam(int time, dev_t * dev_team);


The ft_gamejam() function allocates sufficient time for a developer or team of developers dev_team to create a game and submit it. The game may be subsequently developed further as an argument in function free_time(1).

If insufficient time is allocated, the developer returns NULL.

If ft_gamejam returns game, game is added to array sorted by function peer_vote(1). If final index of game is less than or equal to 4, then game is sent to Facebook where developer dev_team has chance of setting its on_instant_games_platform flag set to 1.

Default value for time is set to 7 days.
